Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world.  About 1C of total warming.  Second chart:  about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability.  Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases.  About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

The Senate and House versions of the Republican tax bill would reverse efforts to modernize the energy system and reduce greenhouse emissions.

I'll note that key components, notably magnets for wind turbines, and cells for solar panels, are almost entirely made in China, and the GOP has also ended support for making them in the US. So this is effectively a total prohibition on new wind and solar after 2027.

The current Senate draft of the US budget bill not only ends subsidies for wind and solar, but imposes a new tax of 30% or 50% of value on them, including on home rooftop solar, with any meaningful foreign-made components. You can't do any of this anymore without foreign-made components because the GOP is also gutting support for US manufacturing. Doing this is going to make US decarbonization effectively impossible.

If you're an American, call your representative and senators and tell them to vote down the bill so long as this is in it.

Not much in the way of other coverage of this yet.

I'll note that the current text of the bill doesn't just get rid of tax credits; it actively imposes taxes on wind and solar to negate their cost advantage over fossil fuels.

The growing recognition of the environmental impact of health care has led to increased efforts to develop sustainable practices.1 Hospitals are major contributors to greenhouse gas emissions and pollution, with intensive care units (ICUs) often generating the most waste. This issue has driven the rise of the concept of green ICUs in high-income countries (HICs);2 initiatives to create green ICUs are focusing on incorporation of advanced technologies, reduction of medical and electronic waste, and optimisation of resource use. Ironically, low-income and middle-income countries (LMICs) have long embraced frugality and sustainability in health care and critical care—out of necessity, not choice. These practices are now being rebranded by HICs under the banner of green ICUs, including many resource-conscious approaches that have been integral to LMIC ICUs for decades. Here, we highlight examples of sustainable ICU and health-care practices in LMICs, challenging the prevailing narrative and advocating for a more inclusive approach to sustainable critical care.
